The invention discloses a control device of a vehicle air conditioner, a bus air conditioner and a control method of the bus air conditioner, the device comprises a rectification unit and a bus capacitor unit, the rectification unit and the bus capacitor unit are used for rectifying and stabilizing induced voltage of a metal piece of the vehicle air conditioner to obtain direct current bus voltage; the sampling unit is used for sampling the direct-current bus voltage output by the bus capacitor unit to obtain direct-current sampling voltage of the induction voltage of the metal part of the vehicle air conditioner; the control unit controls at least one of the inversion unit and the absorption unit to work according to the direct current sampling voltage of the induction voltage of the metal piece of the vehicle air conditioner, and negative compensation is conducted on the induction voltage of the metal piece of the vehicle air conditioner through the inversion alternating current voltage output by the inversion unit. The absorbing unit is used for absorbing the induced voltage of the metal piece of the vehicle air conditioner. According to the scheme, the induced voltage of the bus air conditioner is eliminated in a negative compensation and absorption mode, the harm of the induced voltage of the bus air conditioner to the safety of a human body is reduced, and the running safety and reliability of the vehicle air conditioner are improved.

    本发明公开了一种车用空调的控制装置、大巴空调及其控制方法,该装置包括:整流单元和母线电容单元,对车用空调的金属件的感应电压进行整流和稳压,得到直流母线电压;采样单元,对母线电容单元输出的直流母线电压进行采样,得到车用空调的金属件的感应电压的直流采样电压;控制单元,根据车用空调的金属件的感应电压的直流采样电压,控制逆变单元和吸收单元中的至少之一工作,利用逆变单元输出的逆变交流电压对车用空调的金属件的感应电压进行负补偿,利用吸收单元吸收车用空调的金属件的感应电压。该方案,通过采用负补偿和吸收的方式消除大巴空调的感应电压,降低大巴空调的感应电压对人体安全造成的危害,提高车用空调运行的安全性和可靠性。
